Low-level laser therapy in the management of skin wound healing

Abstract

Introduction: Tissue repair and skin wound healing are complex processes that involve a series of dynamic events, including coagulation, inflammation, granulation tissue formation, wound contraction and tissue remodeling. The need to care for patients with difficulties in wound healing is a growing challenge and requires innovative strategies. One approach that stands out in the treatment of these injuries is low-power laser therapy. This study aims to demonstrate the applicability and results of a low-power laser therapy protocol in the management of skin wound healing. Methods: This is a retrospective case review study reporting the use of laser in the treatment of skin wounds in a single center. Results: We evaluated the results of the implementation of this low-power laser therapy protocol and reported five cases of patients with skin wounds that did not improve with conventional treatment. The lesions were located in different places, with lesions on the trunk, upper limb and lower limb. The five cases showed a good response to laser therapy, evolving with wound healing in a short period of time, with an average healing time of 48 days. Conclusion: It is concluded that low power laser therapy when applied to skin wounds suggests a beneficial, promising action and has the potential to increase the therapeutic options available to the surgeon, however as we report a number of five cases, further studies are needed for check laser efficiency on wounds.
